Abstract

ABSTRAKTujuan penelitian ini adalah untuk meningkatkan prestasi belajar melalui penerapan kombinasi metode pembelajaran Problem Posing dan Resitasi pada pembelajaran akuntansi di Madrasah Aliyah Surakarta.Penelitian ini merupakan Penelitian Tindakan Kelas (PTK) yang dilaksanakan di Madrasah Aliyah Surakarta. Subjek penelitian adalah guru dan siswa kelas XI IPS 1 Madrasah Aliyah Surakarta yang berjumlah 24 siswa. Sumber data berasal dari guru, siswa, dan mitra kolaborator. Teknik pengumpulan data adalah tes, observasi, dokumentasi, dan catatan lapangan. Validitas data menggunakan Validitas isi. Analisis data menggunakan teknik analisis data kuantitatif dan analisis data kualitatif.Hasil penelitian menunjukkan bahwa melalui penerapan metode kombinasi Problem Posing dan Resitasi dapat meningkatkan prestasi belajar siswa dari pra siklus hingga siklus II. Proses pembelajaran pada pra siklus masih terpusat pada guru sehingga siswa tidak terlibat secara aktif dalam proses pembelajaran. Dari hasil observasi pada pra siklus persentase kinerja guru sebesar 48,77%, prestasi aspek kognitif sebesar 45,83% dan aspek afektif sebesar 49,72%. Pada siklus I penggunaan metode kombinasi Problem Posing dan Resitasi dapat meningkatkan kinerja guru sebesar 68,52%, prestasi belajar akuntansi siswa aspek kognitif meningkat menjadi 62,50%, dan aspek afektif meningkat menjadi 68,33%. Pelaksanaan siklus II menyebabkan peningkatan pada kinerja guru sebesar 79,17%, prestasi belajar aspek kognitif siswa meningkat sebesar 79,17% dan aspek afektif siswa meningkat menjadi 76,67%.Simpulan penelitian ini adalah penerapan metode kombinasi Problem Posing dan Resitasi dapat meningkatkan prestasi belajar pada pembelajaran akuntansi di Madrasah Aliyah Al Islam Jamsaren Surakarta.Kata Kunci : Problem Posing, Resitasi, prestasi belajar. ABSTRACTThe objective of the research is to increase the student’s achievement in accounting subject at MA Al Islam Jamsaren Surakarta using Problem Posing and Recitation.This research was categorized into Classroom Action Research (CAR) which was implemented at MA Al Islam Jamsaren Surakarta. The subjects of this research were the 24 students of XI IPS MA Al Islam Jamsaren Surakarta. The sources of the data were teacher, students and collaborator. Data collecting techniques used in this research were test, observation, documentation and field note. Data validity used in this research was content validity. Data analyzing techniques used in this research were quantitative and qualitative technique.The research finding showed that the implementation of Problem Posing and Recitation could increase the student’s achievement from pre-cycle until after cycle II. The learning process in pre-cycle was still teacher-centered, so the students were not active in the learning process. From the result of observation in the pre-cycle, the presentation of teacher’s performance was 48.77%, cognitive achievement was 45.83%, and affective achievement was 49.72%. At cycle I, the use of Problem Posing and Recitation could increase the teacher’s performance that was 68.52%, the students’ achievement in accounting subject for cognitive aspect was 62.50%, and affective aspect was 68.33%. At cycle II, the increasing of teacher’s performance was 79.17%, the increasing of students’ achievement for cognitive aspect was 79.17%, and affective aspect was 76.67%.The conclusion of the research is the implementation of Problem Posing and Recitation can increase the students’ achievement in accounting Subject at Madrasah Aliyah Al Islam Jamsaren Surakarta.Keywords: Problem Posing, Recitation, Students’ Achievement

Abstract

The recycling of residual agricultural biomass using anaerobic digestion allows for the recovery of biomass carbon and nutrients as sources of energy and fertilizer. The obstacles that are encountered in this process include the lignocellulosic structure of biomass tissue and its high carbon-to-nitrogen (C:N) ratio. This study evaluates the co-digestion system of pretreated sorghum stalks and wastewater sludge. The stalks were pretreated by partial bio-oxidation to improve their bacterial accessibility. The digesters were fed a mixture of stalk and sludge at ratios of 100:0, 80:20, 60:40, and 40:60 (total solids [TS] basis). The digesters were run in batches at 35-36 °C, with an initial TS of 15%. The digesters’ performance was evaluated in terms of biogas production rate and yield. The digesters that were run with feed ratios of 80:20 and 60:40 showed shorter lag phase, higher biogas generation rates, and higher biogas yields compared to those run with feed ratios of 100:0 and 40:60. The highest specific biogas production (of 122 L/kg TS) was achieved by the digesters run at ratios of 80:20 and 60:40. The digesters run only with stalks (ratio 100:0) resulted in specific gas production of 67 L/kg TS, whereas those fed on a feed ratio of 40:60 generated only 13 L/kg TS. We conclude that the co-digestion of sorghum stalks and wastewater sludge at a proper ratio improves biogas production.
